Let’s say you want to embed straight JavaScript code in your application.
pom.xml:
<dependency> <groupId>org.mozilla</groupId> <artifactId>rhino</artifactId> <version>1.7.7.1</version> </dependency>
*.Java
import org.mozilla.javascript.*;
private static org.mozilla.javascript.Context cx = org.mozilla.javascript.Context.enter();
private static ScriptableObject scope = cx.initStandardObjects();
private static Function fct;
//You put the key to register in JavaScript and pass the variable in
scope.put(KEY, scope, VARIABLE);
cx.evaluateString(scope, JAVASCRIPTCODE, "script", 1, null);
fct = (Function)scope.get(METHOD_IN_CODE, scope);
Scriptable mapper = cx.newObject(scope);
//If you wanted to use this in the mapper as an example you would pass the key, value and context to the JavaScript function. That way when you write to the context in JavaScript it writes it to the applications context.
fct.call(cx, scope, mapper, new Object[] {key, value.toString(), context});
